{"version":"1.0","type":"rich","title":"map","description":"This visualization displays a world map where each country is colored according to its population using a sequential yellow-orange-red color scale. Population data is loaded from a CSV file and merged with country geometries from the world-atlas TopoJSON dataset. The map uses a Mercator projection via d3.geoMercator and renders paths with d3.geoPath, while hovering over a country reveals its name and population in a tooltip. Missing data appears gray, and the SVG canvas includes a light blue background.","provider_name":"VizHub AI Studio","provider_url":"https://vizhub.com","html":"<iframe src=\"https://vizhub.com/viz/da2767f927ca4f7b8d0dba9d07bc7aa3?mode=embed\" width=\"960\" height=\"500\" scrolling=\"no\" frameborder=\"0\"></iframe>","width":960,"height":500,"cache_age":3600}
